If 6th March, 2005 is Monday, what was the day of the week on 6th March, 2004?
Answer: Option
Explanation:
The year 2004 is a leap year. So, it has 2 odd days.
But, Feb 2004 not included because we are calculating from March 2004 to March 2005. So it has 1 odd day only.
The day on 6th March, 2005 will be 1 day beyond the day on 6th March, 2004.
Given that, 6th March, 2005 is Monday.
6th March, 2004 is Sunday (1 day before to 6th March, 2005).

It is so easy.
One year less from March 2004 to March 2005. It is not including Fab 2004. So it is one year mean 1 odd day. 6 March 2005 is Monday so 6 March 2004 will be Sunday.

As cover a year i.e 365 days.
365/7 52 week and 1 day remaining.
So we can say before 1 day from monday i.e Sunday.

The answer provided here is wrong. Correct answer is SATURDAY as 2004 is a leap year. It has 2 odd days. So each date will be forward by 2 weekdays.

Why didn't we add odd days of 2005.
31+28+6/7=2 odd days.
And there is 1 odd day of 2004.
So there are 3 odd days.
What to do ?
31+28+6/7=2 odd days.
And there is 1 odd day of 2004.
So there are 3 odd days.
What to do ?

Yes this answer is absolutely correct ! because if there is given questions like this, in which it is given difference of 365 days that is 1 year there is always a difference of 1 day but if there is a difference of 366 days that is a leap year it becomes a difference of 2 days.

Anybody please tell me how to find leap year?

Any given year is divisible by the number 4 is a leap year, pretty simple.
For e.g 2008/4 = 502 (NO REMAINDER).
2007/4 = 501.75 (REMAINDER).
Just do observe it's too simple.

Hi @Roji I can explain by your formula.
Day+Month code+(x-1990)+(x-1990)/4.
Step 1: First you should calculate the day for the first mentioned date.
i.e 4 for 6th march 2005.
[6+4+105+26=141/7 it should be Sunday since rem is 1].
But it was given Monday so it is shifted by one day.
Step 2: If you calculate for 6th mar' 2004 you will get Saturday.
So to get answer you should shift the obtained answer by one day. It works for all problems.

Answer is wrong. Its Saturday. Check in calendar. 2004 is leap year so odd days should be 2 not 1.

Guys even you can find through vedic maths.
I show you there are codes for solving calendar problems:
Months:
Jan (1) , feb (4) , mar (4) , apr (0) , may (2) , jun (5) , jul (0) , aug (3) , sep (6) , oct (1) , nov (4) , dec (6). Learn it through any trick.
Weeks:
Sun (1), mon (2), tues (3) fri (6), satur (0 or 7).
Start:
Check if condition: 6th march 2005.
Step : 6 (date) + 4 (march code) + 05 (year) + 05 (date) /4 = 6+4+5+1 = 16/7 = 2 odd days means (monday) but year is 20th century so, -1 is apply that's means 2 - 1 = 1 odd day which means sunday. But option said monday that's means add +1 means 1+1 = 2 odd days (monday).
Check then condition: 6th march 2004.
Step : 6 (date) + 4 (march code) + 04 (year) + 04 (year) /4 = 6+4+4+1 = 15/7 = 1 odd days means (sunday) but year is 20th century so, -1 is apply that's means 1-1 = 0 odd (saturday) but 2004 is leap year means again -1 that's means 6 odd (friday) but from if condition we add +1 at last according to question. It means we will +1 here also then 6 + 1 = 7 or 0 odd day means saturday.
All the best guys.
